Numerical Simulation of Ballistic Impact on Different Types of Helmets

31st International Symposium on Ballistics, 2019
The paper deals with numerical simulation of the response of the three types of helmets (combat helmets, helmets for military policeman and helmet for the paratroopers) to ballistic impact by the fragment simulating projectile (1.1 g). All tested helmets were made from aramid laminate.

Apollo 12 Lunar Module Impact: Laboratory Simulation and Possible Downrange Ballistic Effects

Science, 1970
Plastic pellets were fired into sand targets at a launch angle of 4 degrees and a velocity of 1.68 kilometers per second, the conditions of the Apollo 12 lunar module impact. Shallow elliptical or doublet craters were formed, similar to certain lunar craters.

Three-Dimensional Modelling and Simulation of Ballistic Impact

2001
Abstract : The overarching theme of the work originally proposed concerned the development of three-dimensional computational capability enabling the lagrangian simulation of armor penetration. The principal objectives of the work, as stated in the proposal, were: (1) The development of three-dimensional computational capability including adaptive ...

Simulation of ballistic impact on fabric armour using finite-element method

Journal of the Textile Institute, 2009
This study presents an analytical model to calculate the residual velocity of projectile-penetrating targets composed of planar plain-woven fabric. A non-linear, explicit, three-dimensional finite-element code in ABAQUS 6.4 software is used to simulate the response of plain-woven fabric under high-speed projectile impact.

A Simple Analytical Model to Simulate Textile Fabric Ballistic Impact Behavior

Textile Research Journal, 1997
Composite materials have become very attractive as personal and vehicle armors because of their light weight and high performance. Unfortunately, these materials are difficult to simulate numerically or analytically, and the only way to check their performance is experimentally.

Finite element simulation of ballistic impact on single jersey knit fabric

Composite Structures, 2017
Abstract Knitted fabrics are constructed from interlocking loops of yarn. Curvature in the yarn provides stretchability, making them well suited for garments that will cover areas of the body that require large relative motion. Although most current soft armors are composed of woven textiles, knitted fabrics made of aramid fibers such as Kevlar may ...

Response Simulation of a Micro Reinforced Concrete Target Under Ballistic Impact

International Journal for Computational Methods in Engineering Science and Mechanics, 2014
The response of concrete structures subjected to impact loading has received extensive attention in both civil and military applications. Research on improving the shock resistance of concrete has led to the development of cementitious composites. Micro Reinforced Concrete (MRC), a type of cementitious composite, is a concrete matrix embedded with ...

Thick AA7020-T651 plates under ballistic impact of fragment-simulating projectiles

International Journal of Impact Engineering, 2015
Abstract The ballistic performance of an Al alloy AA7020-T651 (AlZn4.5Mg1, 3.4335) against fragment-simulating projectiles (FSPs) is investigated at impact velocities between 900 m/s and 1500 m/s. The target plates are considered as thick regarding the ratio between the specimen thickness (40 mm) and the projectile diameter (20 mm).

Towards reliable simulations of ballistic impact on concrete structures

2013
Protection against weapon effects like ballistic impacts, fragmenting shells and explosions is the core business of the Explosions, Ballistics and Protection department of TNO (The Netherlands). Experimental and numerical research is performed to gain and maintain the knowledge to support the Dutch MoD and the industry to evaluate and develop adequate ...
